Japan New Companies Monitor — Daily List of New Companies in Japan

Get a clean, English-labelled list of new companies in Japan, straight from the official corporate number registry (法人番号, run by the National Tax Agency). Pick a date range, prefectures and legal entity types, and the Actor returns one structured row per newly incorporated company.

No API key, no registration in Japan. Other registry tools require you to apply for your own application ID with the National Tax Agency (NTA), which is hard to do from outside Japan. This Actor reads a daily, pre-processed copy of the registry, so you can start with one click.

What can you use it for?

• Lead generation: new companies need banks, accountants, insurance, office space, software and recruiting.
• KYB / onboarding checks: confirm that a counterparty really exists and when it was registered.
• Market research: count new incorporations by prefecture, city or entity type over time.
• Monitoring: schedule a daily run and push new companies to your CRM, spreadsheet or Slack with an integration.

What data does it return?

Each dataset item is one newly incorporated company:

Field	Description
corporateNumber	13-digit Japanese corporate number (法人番号)
name	Registered company name, in Japanese
nameKana	Reading of the name in katakana (when available)
nameEn	English name registered with the NTA (rarely available)
entityTypeCode	NTA entity type code (301 Kabushiki Kaisha, 305 Godo Kaisha, ...)
entityType / entityTypeEn	Entity type in Japanese and in English
prefecture / prefectureEn	Prefecture of the registered head office, in Japanese and in English
city / street	City or ward, and the rest of the registered address
address	Full address (prefecture + city + street)
prefectureCode / cityCode	JIS municipality codes (2 + 3 digits)
postalCode	Postal code (NNN-NNNN)
assignmentDate	Date the corporate number was assigned — a close approximation of the incorporation date
sameAddressCompanyCount	Number of other companies registered on the same block (chome / banchi). A high number often means a shared or virtual office address. Buildings are not distinguished
sameNameCompanyCount	Number of other companies with exactly the same name
sourceUrl	The company's page on the NTA Corporate Number Publication Site
collectedAt	When that page was fetched

Empty values are null, never empty strings.

No personal data and no contact details (representative names, email, phone) are included — only public registry facts.

Which companies are included?

Companies whose corporate number was newly assigned on the selected dates and that are still active. Closed registrations and records withheld from publication are excluded.

How to use it

1. Click Try for free.
2. Leave Date from and Date to empty to get the last 7 days (Japan time), or pick a range of up to 366 days.
3. Optionally pick Prefectures (empty = all of Japan) and Entity types (empty = all).
4. Optionally set Max items to cap the output (and your cost).
5. Run the Actor and download the results as JSON, CSV, Excel or via the API.

Tip — daily monitoring: schedule the Actor every morning with empty dates. Each run returns the last 7 days, so de-duplicate on corporateNumber, or set Date from and Date to to yesterday.

When is the data updated?

The registry is published with a delay of about one business day, and the copy is refreshed daily. When your range includes days that are not published yet, the run finishes normally and its status message lists those days. There are no new incorporations on weekends and public holidays.

Input example

{
  "dateFrom": "2026-09-01",
  "dateTo": "2026-09-30",
  "prefectures": ["13", "27"],
  "entityTypes": ["301", "305"],
  "maxItems": 5000
}

Prefectures use the JIS X 0401 code ("01" Hokkaido … "13" Tokyo … "27" Osaka … "47" Okinawa). The input form shows the English names.

How much does it cost?

This Actor uses pay-per-event pricing:

Event	When it is charged	Price
Actor start	Once per run	$0.00005 per GB of memory (a default 256 MB run is charged one event)
new-company	Once per company written to the dataset	$3.00 per 1,000 companies ($0.003 each)

Examples: 100 companies cost $0.30, 5,000 companies cost $15.00. A run that finds no companies costs only the start event. Use Max items or the maximum total charge of a run to cap your spending.

FAQ

How is this different from "Japan Corporate Registry Diff"? That Actor covers five kinds of registry changes (new incorporations, name changes, relocations, closures, mergers) and needs your own NTA application ID. This Actor covers new incorporations only, needs no ID, and adds the same-address and same-name counts.

Is the assignment date the incorporation date? Almost. A corporate number is assigned when the company is registered, so the dates match in most cases, but the registry does not publish the incorporation date itself.

Is this data legal to use commercially? The data is public information released by the National Tax Agency. Its terms of use follow the Public Data License (公共データ利用規約 第1.0版), which requires attribution and a note when data is processed. Please review the terms for your own use case, and follow the laws that apply to your use (for example anti-spam laws for marketing). See the attribution below.

Limitations

• New incorporations only. Name changes, relocations, closures and mergers are not included.
• Date range: up to 366 days per run, no future dates.
• Japanese text: names and addresses are returned as registered, in Japanese. Field names and the entity type / prefecture labels are in English.
• No industry, phone, website or representative data.
• sameAddressCompanyCount / sameNameCompanyCount may be null when the reference snapshot of the whole registry is not fresh enough to count reliably.
